With 1.0.0 to achieve autofocus you can use:

DisposableEffect(Unit) {
    focusRequester.requestFocus()
    onDispose { }
}

In this way the system grants focus to the component associated with this FocusRequester. For example:

val focusRequester = FocusRequester()
TextField(
    //...
    modifier = Modifier
        // add focusRequester modifier 
        .focusRequester(focusRequester)
)

Nice, it works but it doesn't shift the screen up if the keyboard would cover the `TextField` unfortunately... any fix for that? – Andrei Mesh Mar 29 '21 at 14:49

val keyboardController = LocalSoftwareKeyboardController.current and keyboardController?.show() before onDispose – Slava Glushenkov Apr 11 '21 at 07:44
why you don't remember `FocusRequester`? it should be `remember { FocusRequester() }` – user924 Mar 16 '23 at 11:56
if `DisposableEffect.onDispose` method isn't used then just use `LaunchedEffect` instead – user924 Mar 16 '23 at 11:56

This sample shows how to request focus on the next view.

To achieve autofocus on first view on the screen, I believe this can be used:

// ... composable context...

onActive(callback = {
    focusModifiers.first().requestFocus()
})

// ... composable context...
